BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention is related to a structure of raised access floor for networks, and especially to a structure of raised access floor that is structurally simple, steady and easy for positioning after assembling, not subjected to influencing of an uneven ground and having good grounding effect; it is suitable for use for network-line laying out in a house or an office etc.

2. Description of the Prior Art

Distribution and laying out of networks and other kind of lines are very important and necessary. Because each computer can only be connected with a host or connected electrically through a network, the intertwinding of lines becomes more and more complicated when amount of equipment get larger and larger. If lines are exposed outside, they not only look ugly, but also affect walking by of people.

A floor for networks can be elevated for assembling, it leaves a space for threading and distribution of lines; thereby it has been of the main trend for informationalization of modern office. Related raised access floors for networks in the markets presently have much improvement upon those raised access floors developed in the initial stage, and there are various in kinds of products. Referring to FIGS. 12-13 showing a conventional raised access floor for networks, the floor includes a plurality of floor units A and a plurality of raising seats B (the raising seats B can be of the specification as shown in FIG. 12A). Wherein the four peripheral edges of each floor unit A are folded down to form folded flanks A1; the top surface of each raising seat B has a crossed slit B1, each crossed slit B1 can receive therein two folded flanks A1 formed on two floor units A. By the fact that each raising seat B can be used to raise a corner of each of four floor units A, in this way, a large raised access floor for networks can be formed.

In fact, designing of a raised access floor for networks with good quality, in addition to being easy for mold opening and production, shall have the consideration of the convenience in arrangement and positioning in construction in site as well as of the acquiring of stable supporting of the floor units after assembling without being subjected to shaking and influencing of an uneven ground. However, although the aforesaid raised access floor for networks can achieve its object of use, it still has the following defects:

-   1. Its raising seats are each integrally formed to have a fixed     appearance; they cannot be adjusted in pursuance of the unevenness     of a ground. When the ground is uneven in construction, the seats     tend to get upwardly bending corners; and if the ground is recessed,     a case that the floor units are hard to insert for being received     can be induced. -   2. Each slit on a raising seat shall have a width to make tight     mating of two folded flanks on two floor units therein, this makes a     situation that insertion of only one folded flank may induce     loosening that renders the second folded flank hard to insert.     Similarly, when floor units are removed for repairing or line     distribution afterwards, lifting of a floor unit will make loosening     and displacement of the neighboring floor unit relative to its     corresponding seat, this renders construction inconvenient and     accuracy of construction largely reduced. -   3. Electric grounding of the floor units can only be achieved by     mutual contact of the surfaces of the ground with the floor units     after engaging of the folded flanks in the slits, as stated above,     the ground is not completely even, and the thickness of each floor     unit is not completely precise nor uniform, the entire structure     after assembling is subjected to shaking, thereby grounding effect     is not ideal. Especially in those countries using 220 volts     electrically, it is unable to make suitable dealing with grounding.

In view of these, the inventor of the present invention developed a structure of raised access floor for networks based on their professional experience of years on raised access floors to solve the above stated problems.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring firstly to FIGS. 1-5 showing a preferred embodiment of the structure of raised access floor for networks of the present invention, the structure comprises: a plurality of floor units 1 and a plurality of supporting seats 2.

Each of the floor units 1 has four peripheral edges folded down to form folded flanks 11.

The supporting seats 2 are integrally formed of PE or plastic material. Each supporting seat 2 is located beneath the center of four mutually neighboring floor units 1 to support the latter. Such a supporting seat 2 is composed of a crossed member 21 and four pedestals 22 integrally connecting therewith; the crossed member 21 is located to be lower than the tops of the pedestals 22, and has between every two neighboring pedestals 22 a separating piece 211.

Thereby, the four floor units 1 can be separated mutually to have their positions limited by the separating pieces 211 after the folded flanks 11 of the floor units 1 are received in the crossed member 21, and the floor units 1 can be clung evenly on the tops of their corresponding pedestals 22. So that easiness of assembling can be attained, and no loosening or hard receiving during assembling can occur.

Referring again to FIGS. 1-5, when in practicing, the middle sections of the separating pieces 211 can be interrupted (as shown in FIG. 3) in favor of easy insertion of the floor units 1. Each floor unit 1 has on its one peripheral edge an arciform notch 13, so that when two arciform notches 13 of two floor units 1 are juxtaposed with each other, a line outlet 4 is formed (as shown in FIGS. 4, 5). Two “L” shaped stop pieces 212 are provided respectively at the two lateral sides of each of the separating pieces 211 for firm positioning of the floor units 1.

Referring simultaneously to FIGS. 1, 3, wherein each pedestal 22 is hollow; and the supporting seat 2 can be inserted therein with a metal post 4 for reinforcement in supporting. The metal post 4 is cylindrical, and has a plurality of notches 41 spaced away mutually to form a castle-like form. The diagonally opposite four corners of the four pedestals 22 of the supporting seat 2 can be changed to form arciform corner walls 221 to encircle a round space, this can allow insertion of the metal post 4 from below the supporting seat 2. Thereby, the supporting seat 2 can be added therein with the metal post 4 during assembling, this not only can increase firmness of the supporting seat 2, but also can increase the fireproof effect by having the metal material.

In addition to this, to meet the requirement of those countries using 220 volts electrically in grounding, the supporting seat 2 provided in the present invention can be covered with a grounding metal pad-piece 23 on the crossed member 21 of the supporting seat 2 when in manufacturing in a factory (as shown in FIGS. 1, 2), hence in construction, when the floor units 1 are placed in the supporting seat 2, the floor units 1 can be directly pressed upon the grounding metal pad-piece 23 to make grounding of the floor units 1 through the grounding metal pad-piece 23.

As shown in FIGS. 1-5, when in laying out, the metal post 4 is placed from below the supporting seat 2 to render the crossed member 21 in the supporting seat 2 to be abutted against and fixed on the notches 41 of the metal post 4. Then the supporting seat 2 is well placed on the ground, and the floor units 1 can be inserted one by one in the crossed member 21 in the supporting seat 2 (the arciform notches 13 of the floor units 1 all direct to the same center). When in insertion of a floor unit 1, its peripheral folded flanks 11 are limited between their corresponding separating pieces 211 and pedestals 22 to avoid inconvenience of insertion of other floor units 1 induced by loosening of the first floor unit 1. And the floor units 1 can directly press upon the grounding metal pad-piece 23 in insertion, so that the floor units 1 can make grounding through the grounding metal pad-piece 23. When an electrician works in construction, he may make grounding at any of the floor units 1 at a suitable location.

After assembling, if it is desired to repair, a tool can be used to pry a floor unit 1 taking advantage of a corresponding arciform notch 13. And during line distribution, an arciform notch 13 of a floor unit 1 can be changed in direction to make another arciform notch 13 of another floor unit 1 opposite thereto to form a hole 14 (as shown in FIG. 5), this is benefit to drawing out lines thereunder.

Further referring to FIGS. 6-7, to make a better fireproof effect to reach the “0” class fireproof standard, every pedestal 22 can be filled therein with light cement 5, and the bottom of the pedestal 22 can be tightly sealed with an adhesive coating 6, in order that the pedestal 22 can be a closed solid member.

Besides, for the purpose of rendering the grounding metal pad-piece 23 to be placed on the supporting seat 2 more stably, the crossed member 21 in the supporting seat 2 can be provided with a pole 24 protruding upwardly from the central crossed member 21 of the supporting seat 2 for fixedly engaging of the grounding metal pad-piece 23 thereon; the pole 24 is further provided thereon with a locking hole 241.

Further referring to FIGS. 8-11, in addition to the above stated ways of grounding, in the present invention, every peripheral folded flank 11 has at one end a folded piece 15 split therefrom for an angle, the length of the folded piece 15 is larger than that of the folded flank 11. When a floor unit 1 is placed on a supporting seat 2, every folded piece 15 on one of the four peripheral sides can extend over a corresponding separating piece 211 of the supporting seat 2; so that when another floor unit 1 is placed on the supporting seat 2, one of its folded flanks 11 can exactly contact a corresponding folded piece 15. Therefore, plural floor units 1 can make contact with one another to form electric connection. Besides, once one of the floor units 1 is suitably positioned, and a grounding pipe line 16 is mounted and locked, each floor unit 1 electrically connecting with one another can get the grounding effect for the entire raised access floor through the grounding pipe line 16.

Summarily, the present invention thereby has the following advantages:

-   1. The structure of raised access floor for networks of the present     invention is simple structurally and easy for assembling. With the     design of separating pieces, even a single one floor unit can make     itself fixed when it is inserted in, and its corresponding     supporting seat will not be loosened to affect assembling of another     floor unit. The entire structure is very firm after assembling. And     in practical constructional distribution, thickness of the     separating pieces is very thin, and the floor will be added with     articles such as rectangular blankets etc. after construction, no     worry is supposed to have about something will drop or be blocked by     the separating pieces. -   2. Each supporting seat of the present invention is composed of a     crossed member and four pedestals integrally connecting therewith;     hence the entire structure is softer and more flexible, the crossed     member and four pedestals are connected mutually but not completely     fixed nor inflexible, the structure can be adjusted by slight     bending in pursuance of unevenness of a ground to facilitate     assembling in construction. -   3. Each supporting seat of the present invention is provided therein     with a cylindrical metal post to largely increase the firmness of     the supporting seat. And the metal material can increase the     fireproof effect of the supporting seat. Alternatively, each     pedestal can be filled therein with light cement, and the bottom of     the pedestal can be tightly sealed with an adhesive coating to get     an even better fireproof effect to reach the “0” class fireproof     standard. -   4. Each supporting seat of the present invention is covered with a     grounding metal pad-piece on the crossed member of the supporting     seat when in manufacturing in a factory, hence in construction,     floor units can be directly pressed upon the grounding metal     pad-piece to make ground contacting of the floor units. There is no     need of other construction for grounding; thereby it is very     convenient and time saving in construction. -   5. When in assembling the floor, and during line distribution, it     needs only to change the direction of an arciform notch of a floor     unit to be opposite to another arciform notch of another floor unit     to form a hole, this is benefit to drawing out lines thereunder.

The embodiment given is only for illustrating the present invention, and not for giving any limitation to the scope of the present invention. It will be apparent to those skilled in this art that various modifications or changes without departing from the spirit of this invention shall also fall within the scope of the appended claims.
